SPINNING APPARATUS.

SPECIFICATION forming part of LettersPatent No. 656,954, dated August 28, 1900.

Application filed October 2 3 l 8 9 9 To a/ZZ whom it may concern/ Be it known that I, GEORGE O. DRAPER, o l-Iopedale, county of lVorcester, State of Massachusetts, have invented an Improvement in Spinning Apparatus, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts. The function of the spindle in spinning 1o apparatus is at present merely to effect rotation of the yarn carrier or bobbin, the rotary motion transmitted to the spindle being by it imparted to the yarn-carrier as the two are held in frictional engagement. Hereto'fore the spindle has been considered a necessary feature of such apparatus, and the only important modification is that usually known as the dead-spindle type, in which a stationary upright is utilized to carry or form an. axial support for a revolving shell on which the yarn-carrier is placed. In the course of my experiments to simplify the construction and cheapen the cost of spinning apparatus, with due regard to efficiency, I have been led 2 5 to the conclusion that the yarn-carrier should be itself rotated directly upon an upright axial support, thereby doing away with the intermediate shell of the dead-spindle type, and thus eliminating entirely the spindle I have practically embodied my invention in anumber of different constructions, to be made the subject-matter of other applications, and herein I have shown a very simple form of spinning apparatus, the yarn-carrier fitting an axial support therefor with a running fit and being provided with a suitable groove for the reception of the usual driving-band. In this as in other embodiments of myinvention the yarn-carrier is preferably treated with some suitable antifriction compound and the question of wearis one of relatively-small moment. Warp-bobbins rarely last with ordinary handling much longer than a year, and they are 5 on the spinning-frame but half of that time, and it has been proved that a wooden bearing properly treated with an antifriction composition can run at present spindle speed for more than a year without showing extreme 5o wear. The bearin g parts of the yarn-carrier,

serial No. 734,425. (No niodei.)

therefore, should last as long as does the present bobbin as commonly used.

Figure 1 in side elevation and partly in section represents spinning apparatus embodying one form of my invention. is a partial left-hand elevation of the appa- Fig. 2

ratus shown in'Fig. 1; and Figs. 3, 4, and 5 are details showing the mode of placing the yarn-carrier in operative position and applying the driving-band.

. Referring to Figs. 1 and 2, the cylindrical upright standard or axial support A for the yarn carrier or bobbin B is shown as fixedly mounted in a stand or foot A, adapted to be held on the usual spindle-rail in Well-known lar band-receiving groove b is formed, the walls of said groove flaring from theirline of intersection. The stand A is shown as provided with an upturned guide a, having an opening a therein,through which the drivingband C passes, the'depressions a in the guide 8 supporting the band when applying the yarncarrier.

1 have shown in Figs. 3, at, and 5 successive positions assumed by the yarn-carrier as it is pushed down along the upright support A to enter the bight of the driving-band, the taper b acting to guide the band into the annular groove 1), the elasticity of the band permitting such operation. If desirable, the operative may assist such operation by help ing to guide the band with the fingers or with any suitable tool held in the hand.

It will be noticed that the lower portion of the yarn-carrier issomewhat larger in diameter than the main body portion U thereof 5 to thus make an enlargement at D which serves to support the yarn mass and hold it in position on the carrier. This is not absolutely necessary, but conforms to the usual practice.

ICO

To position a yarn-carrier, a simple downward pressure thereon while the driving-band is guided, as shown in Figs. 3 and 4, is sufficieut.

The tension of the driving-band serves to maintain the yarn-carrier in vertical position on its axial support, or a lateral projection, as a, on the standard A and supported by a spring 5 (see dotted lines, Fig. 1) could be used as a vertical support, while permitting a downward movement of the carrier when applying the band.

The yarn-carrier is impregnated along its bore with a suitable antifriction compound by having its pores impregnated with hot wax or grease or with antifriction compounds of suitable composition which resist wear from the motion about the standard.

Inasmuch as the yarn-carrier is directly controlled by the drivingband and is guided throughoutits length bythe uprightstandard, it can be run at high speed without the vibra tion which a rigid spindle would show at the same speed.

My invention is not restricted to the precise construction and arrangementshown and described, as the same may be varied without departing from the spirit and scope of my in vention.

Having fully described my invention, what u gage the whirl and also to sustain the carrier vertically.

3. An upright standard, a removable yarncarrier adapted to be axially supported thereby and rotated thereon and having an annular groove for the driving-band, and a bandguide, the yarn-carrier being sustained vertically by the tension of the driving-band.

4:. A cylindrical standard, a support therefor having an upturned band-guide, and a removable yarn-carrier adapted to be rotated on the standard and provided with an annular groove for the driving-band, the tension of the band supporting the yarn-carrier Vertically.

5. Spinning apparatus comprehending a fixed upright standard or axial support, a yarn-carrier rotatable thereon and having a contained bearing to travel upon the standard, and rotating and vertically-supporting means for and applied directly to the yarn-carrier, said means also providing the vertical support for the latter.

6. Spinning apparatus comprehending a fixed standard or axial support, a supportingstand therefor having a band-guide, and a yarn-carrier.adapted to receive the yarn directly thereupon and to rotate directly on and in engagement with the standard, said yarncarrier containing bearings and having an integral band-receiving portion.

7. Spinning apparatus comprehending a rotatable yarn-carrier, an axial support therefor, and rotating means to directly engage the yarn-carrier and also sustain it vertically.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
